I have a diving knife encased in a big heavy brass sheath like the one in the 5th photo.It came from the Royal Navy Dockyard “HMS Malabar” in Bermuda where my father used to work in the machine shop.
The knife handle is split due to corrosion of the metal shaft but otherwise in good condition.I wonder what it is worth?

This is Jean – I am 84 years young and new to computor works – please forgive my errors. I was 26 yrs old when my husband was a diver and wore that metal head divers suit. Do you know the name of that metal head? It may not have a name.Jean
